Such as predefined may refer to what is defined in the protocol.

In this embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, may include an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited in this application.

To facilitate a better understanding of the embodiments of the present application, a description of related art will be first provided.

In wireless communications, modulation is the primary method of accomplishing signal spectrum shifting. For example, as shown in fig. 2, the mixer may perform nonlinear operation on the low-frequency input signal F1 and the modulated carrier wave F0 to generate a sum frequency signal or a difference frequency signal of the two signals, and select a desired high-order frequency output signal F2 therefrom, that is, complete frequency spectrum shifting from low frequency to high frequency, where the frequency relationship is f2=f1+f0.

For wideband signals, its center frequency point is referred to as the dc carrier position, also referred to as the DC (Direct Current) position, as shown by F1 and F2 in fig. 3.

In a specific implementation, the modulation of the signal is implemented in a radio frequency chip (RFIC) of the terminal device, as shown in fig. 4, a baseband chip (BBIC) of the terminal device inputs a baseband signal to the RFIC, further, in the RFIC, the input low-frequency baseband signal and a local oscillator signal (LO, frequency is F0) of the RFIC are mixed to generate a radio frequency signal, and after being amplified by a Power Amplifier (PA), the radio frequency signal is finally transmitted through an antenna of the terminal device.

In the orthogonal frequency division multiplexing (Orthogonal frequency-division multiplexing, OFDM) modulation scheme, the DC position will usually have stronger signal interference, and the carrier needs to be removed in the receiving end to improve the signal-to-noise ratio of the reception, so the receiving end needs to know the accurate DC position. The DC location is typically signaled to the receiving end by the transmitting end. In the above behavior example, the terminal device needs to inform the network device of the exact DC position of the transmitted signal, so that the network device can accurately remove the subcarrier of the DC position.

In the NR system, in order to save power of a terminal, a BWP concept is introduced, and a network device generally configures a smaller transmission and reception bandwidth for the terminal device, thereby reducing the complexity of transmitting and receiving signals by the terminal device. For example, there may be multiple channels in the entire frequency band, and after the terminal device accesses one channel, the network device may further configure not more than 4 BWP (only one BWP may be activated at the same time), and the terminal device may operate in this activated BWP in subsequent communications. The terminal device may report DC positions based on the configured BWP, and if 4 BWP are configured on a single carrier, the terminal device reports 4 DC positions to the network device at most.

In some scenarios, the terminal device may operate on multiple carriers, each of which may in turn configure multiple BWP's, the specific location of the DC being affected by the specific location of the active BWP on the multiple carriers. As shown in fig. 5, carrier 1 is configured with BWP 1-BWP 4, carrier 2 is configured with BWPx-BWPz, … …, carrier n is configured with BWPa-BWPd, the number of potential BWP combinations is 4*3 × … ×4, and in case of a large number of configured carriers, the number of potential BWP combinations is very large, and in this case, how to report DC positions is an urgent problem to be solved.

It should be understood that, in various embodiments of the present application, the size of the sequence number of each process does not mean that the execution sequence of each process should be determined by its functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

It should be noted that, on the premise of no conflict, the embodiments described in the present application and/or the technical features in the embodiments may be arbitrarily combined with each other, and the technical solutions obtained after the combination should also fall into the protection scope of the present application.

Fig. 6 is a schematic interaction diagram of a method for reporting a dc carrier location according to an embodiment of the present application, as shown in fig. 6, the method 200 may include at least some of the following steps:

s204, the terminal equipment determines at least one direct current carrier position offset;

and S205, the terminal equipment reports the at least one direct current carrier position offset to the network equipment.

In this embodiment of the present application, the dc carrier position offset represents a frequency offset of a dc carrier position used by the terminal device with respect to a reference dc carrier position.

It should be noted that, in the embodiment of the present application, the direct current carrier position or the DC position may be replaced with each other. The direct current carrier position offset is also called DC offset, and the two can be replaced with each other. The reference direct current carrier position or reference DC position may be interchanged.

It should be understood that embodiments of the present application are not limited to the manner in which the DC offset is expressed. The DC offset may be positive, negative, or zero.

As an example, the DC offset may be a specific offset frequency value, such as 5khz,15khz, etc.

As another example, the DC offset may be the number of offset subcarriers, for example, n subcarriers are offset in units of 15khz subcarrier spacing, where n may be positive, negative, or zero.

As yet another example, the DC offset may be an offset number in units of a specific frequency interval, such as in units of frequency intervals of 100khz or 5khz or 15khz or 200khz, etc., by n frequency intervals, where n may be positive, negative, or zero.

Alternatively, in some embodiments, if the terminal device does not send the at least one DC offset to the network device, the network device may consider the DC location actually used by the terminal device to be the reference DC location. Interference cancellation is further performed based on the reference DC position.

In some embodiments, the location of the direct current carrier actually used by the terminal device is the same as the reference DC location, in which case the terminal device may not send the at least one DC offset to the network device.

In other embodiments, the location of the direct current carrier actually used by the terminal device is different from the reference DC location. For example, in a multi-carrier scenario, the DC position of the terminal device is affected by a number of factors, such as the lowest and highest frequency carriers, the lowest and highest frequency active carriers, the lowest and highest frequency BWP, the lowest and highest frequency active BWP, and in some scenarios, the intermediate carrier and intermediate BWP, such as the need to adjust the DC position to avoid internal interference. In this case, the terminal device may report at least one DC offset to the network device, so that the network device may determine a DC position actually used by the terminal device according to the reference DC position and the at least one DC offset, and further perform interference cancellation according to the actually used DC position.

Optionally, in some embodiments, the at least one DC offset may be sent by any uplink message or uplink signaling, such as an uplink radio resource control (Radio Resource Control, RRC) message, medium access control (Media Access Control, MAC) signaling, physical uplink control channel (Physical Uplink Control Channel, PUCCH), etc., which is not limited in this application.

In the embodiment of the application, the terminal device may operate on multiple carriers simultaneously, for example, the terminal device is configured to employ carrier aggregation (Carrier Aggregation, CA) (for example, may include in-band continuous CA and in-band discontinuous CA) or a dual connectivity operation mode.

In the embodiment of the present application, the terminal device may use a single transmission link to support simultaneous operation on the multiple carriers, or may use multiple transmission links to support simultaneous operation on the multiple carriers. In other words, the terminal device may use a single transmission link architecture, or may also use a multiple transmission link architecture, or the multiple carriers correspond to a single transmission link, or to multiple transmission links.

In embodiments of the present application, a transmit chain may be used to implement modulation and power amplification of a carrier signal, and the transmit chain may include a Power Amplifier (PA) and a mixer. In some cases, the transmit chain architecture may refer to employing a PA architecture.

In the embodiment of the present application, the reference dc carrier positions may be one or more.

In some embodiments, in a case where the terminal device adopts a single transmit link architecture, the reference dc carrier location may be one.

For example, as shown in fig. 7, the terminal device is configured with carriers 1 to 4, where the 4 carriers correspond to a single transmission link, and the reference dc carrier position may be one.

In other embodiments, the terminal device adopts a multiple-transmit-link architecture, where the reference dc-carrier location may be multiple, and each transmit link corresponds to one reference dc-carrier location, or the reference dc-carrier location may be one, for example, multiple transmit links correspond to the same reference dc-carrier location.

For example, as shown in fig. 8, the terminal device is configured with carriers 1 to 4, where carrier 1 and carrier 2 correspond to transmission link 1, carrier 3 and carrier 4 correspond to transmission link 2, and the transmission link 1 and transmission link 2 may respectively correspond to respective reference DC positions, for example, transmission link 1 corresponds to reference DC position 1, and transmission link 2 corresponds to reference DC position 2.

In some embodiments, the terminal device adopts a single transmission link architecture, the number of the reference dc carrier positions is one, and the at least one dc carrier position offset includes one dc carrier position offset. The one reference DC carrier position and the one DC carrier position offset are used to determine a DC carrier position used by the single transmit link

In other embodiments, the terminal device employs a multiple transmit link architecture, and the at least one dc-carrier position offset includes a plurality of dc-carrier position offsets, each corresponding to one dc-carrier position offset, each dc-carrier position offset being a frequency offset relative to a same reference dc-carrier position. And the same reference direct current carrier position and the direct current carrier position offset corresponding to each transmitting link are used for determining the direct current carrier position used by each transmitting link.

In still other embodiments, the terminal device employs a multi-transmit chain architecture, each transmit chain corresponding to a reference dc-carrier position, and the at least one dc-carrier position offset comprises a plurality of dc-carrier position offsets, each transmit chain corresponding to one dc-carrier position offset. And the reference direct current carrier position and the direct current carrier position offset corresponding to each transmitting link are used for determining the direct current carrier position used by each transmitting link.

In still other embodiments, the terminal device employs a multi-transmit chain architecture, each transmit chain corresponding to a reference dc-carrier position, and the at least one dc-carrier position offset comprises a dc-carrier position offset. The reference dc-carrier location and the one dc-carrier location offset corresponding to each transmit chain are used to determine the dc-carrier location used by each transmit chain.

In the following, a single transmission link is taken as an example, and a specific implementation manner of the reference DC position of each transmission link is described, and when a plurality of transmission links exist, the implementation manner of the reference DC position of other transmission links is similar, which is not described herein.

Optionally, in some embodiments, the terminal device may determine at least one dc carrier position, where the at least one dc carrier position may be predefined, or may be determined based on a configuration of the network device, or the terminal device may determine itself, which is not limited in this application.

Optionally, in some embodiments, as shown in fig. 6, the method 200 further includes:

s201, the terminal device may report the at least one DC position to a network device.

Optionally, in some embodiments, the at least one dc carrier location is sent through any uplink message or uplink signaling, such as an uplink RRC message, MAC signaling, PUCCH, etc., which is not limited in this application.

The reference dc carrier location may be a dc carrier location of the at least one dc carrier location used to determine a dc carrier location offset. The at least one dc-carrier location may be considered a candidate reference dc-carrier location, which is a target reference dc-carrier location.

Optionally, the reference DC position may comprise part or all of the at least one direct current carrier position.

In some embodiments, the terminal device may report the plurality of DC positions to the network device, further indicating to the network device a reference DC position to be used in determining the DC offset.

That is, the terminal device may report a plurality of reference DC positions to the network device, further indicating to the network device a target reference DC position to be used in determining the DC offset.

In some embodiments, as shown in fig. 6, the method 200 further comprises:

s202, the terminal device may send first indication information to the network device, where the first indication information is used to indicate a reference DC carrier position among the DC carrier positions, i.e. which DC carrier position is used as the reference DC position.

As an example, the first indication information includes a first bit map, where the first bit map includes a plurality of bits, each bit in the plurality of bits corresponds to one dc carrier position in the plurality of dc carrier positions, and a value of each bit is used to indicate whether the corresponding dc carrier position is a reference dc carrier position.

For example, a bit value of 1 indicates yes, a value of 0 indicates no. If the terminal device reports DC positions 0 to 3, the first bit map may include 4 bits, which respectively correspond to one DC position, and if the first bit map is 1000, the first bit map indicates DC position 3 as a reference DC position.

Optionally, in some embodiments, the first indication information is sent through any uplink message or uplink signaling, such as an RRC message, MAC signaling, PUCCH, etc., which is not limited in this application.

Optionally, in some embodiments, as shown in fig. 6, the method further comprises:

s203, the terminal equipment sends first capability information to the network equipment, wherein the first capability information is used for indicating whether the terminal equipment supports reporting of the direct current carrier position under the CA.

Optionally, in some embodiments, the first capability information is sent through any uplink message or uplink signaling, such as an uplink RRC message, MAC signaling, PUCCH, etc., which is not limited in this application.

Optionally, the first capability information may also be used to indicate whether the terminal device supports a reporting manner of an existing DC location or supports a reporting manner of a DC location according to an embodiment of the present application. Alternatively, the first capability information may be used to indicate whether reporting modes based on the reference DC position and the DC offset are supported.

Optionally, in some embodiments, the terminal device may also implicitly indicate to the network device a dc carrier location of the plurality of dc carrier locations as a reference dc carrier location.

For example, the terminal device may implicitly indicate the reference DC position by whether to transmit the first capability information or by the content indicated by the transmitted first capability information.

As an example, if the first capability information indicates that the terminal device supports reporting of a dc carrier location under CA, the reference dc carrier location is a first dc carrier location of the plurality of dc carrier locations.

As another example, if the first capability information indicates that the terminal device does not support reporting of a dc carrier location under CA, in this case, the reference dc carrier location is a second dc carrier location of the plurality of dc carrier locations, where the first dc carrier location and the second dc carrier location are different.

As yet another example, when the terminal device does not send the indication information indicating the reporting capability of the DC position, the reference DC carrier position is a third DC carrier position of the plurality of DC carrier positions.

As yet another example, when the terminal device sends indication information indicating reporting capability of a DC position, the reference DC carrier position is a fourth DC carrier position of the plurality of DC carrier positions, where the third DC carrier position and the fourth DC carrier position are different. Or when the terminal equipment sends the indication information indicating the reporting capability of the DC position, implicitly indicating that the reference DC carrier position corresponds to different DC carrier positions according to different contents of the indication information of the reporting capability.

In some embodiments, the terminal device may determine at least one reference DC position from first information, wherein the first information comprises at least one of:

a band configuration on a terminal device, a carrier configuration on the terminal device, a bandwidth part BWP configuration on the terminal device, an active BWP configuration on the terminal device, wherein the band configuration is used for configuring an operating band of the terminal device, the carrier configuration is used for configuring a plurality of carriers on the operating band, the BWP configuration is used for configuring a plurality of BWP on each carrier of the plurality of carriers, and the active BWP configuration is used for configuring an active BWP of the plurality of BWP.

Alternatively, in the embodiment of the present application, the determination of the reference DC position by the terminal device according to the first information may be determined by the terminal device, or may be based on an indication of the network device, or may be predefined (or default).

Alternatively, the network device may indicate the determination manner of the reference DC position to the terminal device through existing signaling, for example, the determination manner of the reference DC position may be configured to the terminal device through frequency band configuration, carrier configuration, BWP configuration, or the like. Alternatively, the determination manner of the reference DC position may be configured for the terminal device through a new signaling, which is not limited in this application.

It will be appreciated that in some embodiments the manner in which the reference DC position is determined is predefined, in which case the terminal device may be aware of the reference DC position used by the terminal device to determine the DC offset without having to report the reference DC position to the network device.

The manner in which the reference DC position is determined, i.e. the possible positions of the reference DC position, is described below in connection with specific embodiments.

Mode 1

In this mode 1, the terminal device determines the reference DC position according to the frequency band configuration.

In some embodiments, the terminal device may determine that the reference DC location is located at a particular location on the operating frequency band indicated by the frequency band configuration. The specific location may be pre-agreed.

As an example, the reference DC position includes a preset position on the operating frequency band indicated by the frequency band configuration. The preset position on the working frequency band may be, for example, a center frequency point position of the working frequency band. Center frequency point position D1 as shown in fig. 9.

In this case, the DC position reported by the terminal device may not be affected by the carrier configuration, BWP configuration and BWP activation conditions.

Mode 2

In this mode 2, the terminal device determines the reference DC position according to the specific carrier configuration on the terminal device.

In this case, the reference DC position reported by the terminal device may not be affected by the BWP configuration and the BWP activation condition.

Optionally, the specific carrier configuration may be any carrier configuration of all carrier configurations on the terminal device, or may also be a carrier configuration that satisfies a specific condition, for example, a carrier configuration corresponding to a carrier with a minimum carrier number, or may also be a carrier configuration corresponding to a carrier with a maximum carrier number, or the like.

In some embodiments, the terminal device determines the reference DC position from the first carrier. In this case, the reference DC location is a particular location on the first carrier. The specific location may be pre-agreed. For example, the center frequency point position of the first carrier may be the center frequency point position of the first carrier.

For example, as shown in fig. 9, the terminal device is configured with carrier 1 and carrier 2, and the target carrier for determining the reference DC position may be carrier 1 or carrier 2, and thus, the reference DC position may be located at the center frequency point position DC2 on carrier 1, or may also be located at the center frequency point position DC3 on carrier 2.

Optionally, the determining, by the terminal device, the reference DC position by using which carrier configuration may be predefined (or default), for example, by default, by using a carrier configuration corresponding to the carrier with the smallest carrier number, or may be indicated by the network device, or may be determined by negotiating between the network device and the terminal device, or may be determined by the terminal device at the discretion, and further notified to the network device. For example, the terminal device may send second indication information to the network device, the second indication information being used to indicate a target carrier or a target carrier configuration for determining the reference DC position.

It should be understood that the indication manner of the second indication information is not particularly limited in this application.

As an example, the second indication information includes a second bit map, where the second bit map includes a plurality of bits, each bit in the plurality of bits corresponds to one carrier in the plurality of carriers, and a value of each bit is used to indicate whether the dc carrier position is located in the corresponding carrier, for example, a value of 1 indicates yes, and a value of 0 indicates no.

For example, if the terminal device is configured with 8 carrier configurations, the first bit map may include 8 bits (bits 7 to 0) corresponding to the carriers 7 to 0, respectively, and when the reference DC position is on the carrier 1, the bit 1 may be set to 1, and the other bits are set to 0, which indicates that the reference DC position is on the carrier 1.

As another example, the second indication information includes a plurality of bits, different values of the plurality of bits being used to indicate a carrier in which the reference DC position is located.

For example, the terminal device is configured with 8 carrier configurations, and the second indication information may be indicated by using 3 bits, where the 8 values of the 3 bits correspond to the 8 carrier configurations, for example, when the reference DC position is located on the 4 th carrier, the 3 bits is set to 100.

Optionally, in some embodiments, the second indication information is sent through any uplink message or uplink signaling, such as an RRC message, which is not limited in this application.

Mode 3

In this mode 3, the terminal device determines the reference DC position according to the specific activated BWP configuration.

In this case, the reference DC position reported by the terminal device is related to the BWP configuration and the activation situation of BWP.

Alternatively, the specific active BWP configuration may be any BWP configuration among all the active BWP configurations on the terminal device, or may also be a BWP configuration satisfying a specific condition, for example, a BWP configuration corresponding to a BWP with the smallest BWP Identification (ID), or may also be a BWP configuration corresponding to a BWP with the largest BWP ID.

In some embodiments, the terminal device determines the reference DC position from the first BWP, in which case the reference DC position is a specific position on the first BWP. The specific location may be pre-agreed. For example, the center frequency point position of the first BWP may be.

For example, as shown in fig. 9, the terminal device is configured with carrier 1 and carrier 2, BWP activated on carrier 1 is BWP1, BWP activated on carrier 2 is BWPa, and the target BWP used for determining the reference DC position may be BWP1 or BWPa, and the reference DC position may be located at the center frequency point position DC4 of BWP1 or may also be located at the center frequency point position DC5 of BWPa.

Alternatively, the determination of the reference DC position by the terminal device using which active BWP configuration may be predefined (or default), for example, the default use of the BWP configuration corresponding to the BWP with the smallest BWP ID in the active BWP may be indicated by the network device, or may be determined by the network device and the terminal device in a negotiation manner, or may be determined by the terminal device at the discretion, and further notified to the network device. For example, the terminal device may transmit third indication information indicating the target BWP or the target BWP configuration for determining the reference DC position to the network device.

It should be understood that the indication manner of the third indication information is not particularly limited in this application.

As an example, the third indication information includes a third bit map including a plurality of bits, each bit of the plurality of bits corresponding to one of the activated BWP on the plurality of carriers, and a value of each bit is used to indicate whether the reference DC position is located in the corresponding activated BWP.

For example, if the terminal device is configured with 4 active BWP configurations, the third bit map may include 4 bits (bits 3 to 0) corresponding to the 4 active BWP configurations, or corresponding to four carriers, respectively, where when the reference DC position is on the active BWP on the second carrier, bit 1 may be set to 1, and the other bits to 0, indicating that the reference DC position is on the active BWP on carrier 1.

As another example, the third indication information includes a plurality of bits, and different values of the plurality of bits are used to indicate the BWP where the reference DC position is located.

For example, if the terminal device is configured with 4 BWP configurations, the third indication information may be indicated with 2 bits, where the 4 values of the 2 bits correspond to the 4 BWP configurations, for example, when the reference DC position is located at the active BWP on the 2 nd carrier, the 2bit is set to 010.

Optionally, in some embodiments, the third indication information is sent through an uplink RRC message, or may also be sent through other uplink messages or signaling, which is not limited in this application.

In some embodiments, the terminal device may determine the reference DC configuration according to a frequency band range occupied by a plurality of carriers.

It should be understood that in the embodiments of the present application, the frequency band occupied by each of the plurality of carriers may be continuous or may be discrete. In some embodiments, the frequency range occupied by the multiple carriers may be, for example, a union of the frequency ranges occupied by each carrier, or may also be a frequency range between the lowest frequency point and the highest frequency point occupied by the multiple carriers. I.e. the frequency band range occupied by the plurality of carriers may be a discrete plurality of sub-frequency band ranges or may be a continuous frequency band range.

As an example, the reference DC position includes a preset position in a first frequency band range, where the first frequency band range is a frequency band range occupied by the plurality of carriers.

In one case, the first frequency band range is a continuous frequency band range, and in this case, the preset position in the first frequency band range may be a center frequency point position of the first frequency band range. For example, as shown in fig. 10, the terminal device is configured with carrier 1 and carrier 2, the frequency range from the lowest frequency point to the highest frequency point occupied by carrier 1 and carrier 2 is a first frequency range, and the reference DC position may be a center frequency point DC6 of the first frequency range.

In this mode 6, the terminal device determines the reference DC position from all BWP configurations on a specific carrier.

In this case, the reference DC position reported by the terminal device is related to the BWP configuration but is not affected by the activation situation of the BWP.

Alternatively, the specific carrier may be any carrier of all carriers on the terminal device, or may also be a carrier that satisfies a specific condition, for example, a carrier with a minimum carrier number, or may also be a carrier with a maximum carrier number, etc.

Alternatively, the determination of the reference DC position by the terminal device using all BWP configurations on which carrier may be predefined (or default), for example, the default use of the BWP configuration on the carrier with the smallest carrier number may be indicated by the network device, or may be determined by the network device and the terminal device in a negotiation manner, or may be determined by the terminal device at the discretion, and further notified to the network device. For example, the terminal device may send third indication information to the network device, where the third indication information is used to indicate a target carrier for determining the reference DC position. The specific indication manner refers to the related description of the second indication information in the manner 2, and for brevity, a detailed description is omitted here.

In some embodiments, the terminal device may determine the reference DC configuration according to the frequency band range occupied by all BWP on the specific carrier.

Similar to the frequency band ranges in the modes 4 and 5, the frequency band ranges occupied by all BWP on the specific carrier may be discrete multiple sub-frequency band ranges, or may be a continuous frequency band range, for example, a frequency band range between the lowest frequency point and the highest frequency point occupied by all BWP on the specific carrier.

As an example, the reference DC position includes a preset position in a third frequency band range, where the third frequency band range is a frequency band range occupied by a plurality of BWP configured on a second carrier of the plurality of carriers.

In one case, the third frequency band range is a continuous frequency band range, and in this case, the preset position in the third frequency band range may be a center frequency point position of the third frequency band range. For example, as shown in fig. 11, the terminal device is configured with carrier 1 and carrier 2, on carrier 1 is configured with BWP1 to BWP4, on carrier 2 is configured with BWPa to BWPd, and the third frequency band range may be a frequency band range from the lowest frequency point to the highest frequency point occupied by the BWP on carrier 1, or may be a frequency band range from the lowest frequency point to the highest frequency point occupied by the BWP on carrier 2, and the reference DC position may be located at a center frequency point position DC8 of the frequency band range occupied by the BWP on carrier 1, or may also be located at a center frequency point position DC9 of the frequency band range occupied by the BWP on carrier 2.

In another case, the third frequency band range includes a plurality of discrete sub-band ranges, and in this case, the preset position in the third frequency band range may include a center frequency point position of each of the plurality of discrete sub-band ranges.

Mode 7

In this mode 7, the terminal device determines the reference DC position from all BWP configurations on the plurality of carriers.

In some embodiments, the terminal device may determine the reference DC configuration from a frequency band range occupied by all BWP on multiple carriers on the terminal device.

Similar to the frequency band ranges in modes 4 to 6, the frequency band ranges occupied by all BWP on the plurality of carriers may be discrete multiple sub-frequency band ranges, or may be a continuous frequency band range, for example, a frequency band range from the lowest frequency point to the highest frequency point occupied by all BWP on the plurality of carriers.

As an example, the reference DC position includes a preset position in the fourth frequency band range, where the fourth frequency band range is a frequency band range occupied by a plurality of BWP configured on the plurality of carriers.

In one case, the fourth frequency band range is a continuous frequency band range, and in this case, the preset position in the fourth frequency band range may be a center frequency point position of the fourth frequency band range. For example, as shown in fig. 11, the terminal device is configured with carrier 1 and carrier 2, carrier 1 is configured with BWP1 to BWP4, carrier 2 is configured with BWPa to BWPd, the fourth frequency range may be a frequency range from the lowest frequency point to the highest frequency point occupied by BWPa to bwpp 4 and BWPa to BWPd, and the reference DC position may be located at the center frequency point DC10 of the fourth frequency range.

In another case, the fourth frequency band range includes a plurality of discrete sub-band ranges, and in this case, the preset position in the fourth frequency band range may include a center frequency point position of each of the plurality of discrete sub-band ranges.

Mode 8

In this mode 8, the terminal device may determine the reference DC position as the specific frequency point position.

For example, any frequency point in the operating frequency band, or any frequency point in the active BWP, or any frequency point location on a certain carrier, etc.

In this manner 9, the terminal device may determine the reference DC position according to a first carrier and a second carrier in a first carrier set, where the first carrier is a carrier with a lowest frequency in the first carrier set, and the second carrier is a carrier with a highest frequency in the first carrier set.

Example 1: the first carrier set includes a plurality of uplink carriers configured by the network device.

For example, as shown in fig. 12, the terminal device is configured with uplink carriers 1 to 3, the uplink carrier with the lowest frequency is carrier 1, and the uplink carrier with the highest frequency is carrier 3, and the reference DC position may be a specific position between the uplink carrier 1 and the uplink carrier 3, such as a center frequency position DC position 1.

Example 2: the first set of carriers includes a plurality of uplink carriers configured and activated by the network device.

For example, as shown in fig. 12, uplink carriers 1 to 3 are configured on the terminal device, the activated uplink carriers are uplink carrier 1 and uplink carrier 2, the uplink carrier with the lowest configured and activated frequency is carrier 1, the uplink carrier with the highest configured and activated frequency is carrier 2, and the reference DC position may be a specific position between the uplink carrier 1 and the uplink carrier 2, such as a center frequency position DC position 2.

Alternatively, in this example 1 and example 2, the uplink transmission and the downlink reception of the terminal device are not in common DC positions, i.e., the uplink transmission and the downlink reception of the terminal device employ independent DC positions. The independent DC positions are adopted for uplink and downlink, so that the influence of downlink CA on the uplink DC position is avoided.

Example 3: the first carrier set includes a plurality of uplink carriers configured by the network device and a plurality of downlink carriers configured by the network device.

Example 4: the first set of carriers includes a plurality of uplink carriers configured and activated by the network device and a plurality of downlink carriers configured and activated by the network device.

Alternatively, in this example 3 and example 4, the terminal device transmits and receives the common DC position in the uplink and downlink, in which case the influence of the downlink carrier needs to be considered in determining the uplink DC position.

Example 2: the first BWP set comprises all upstream BWP configured and activated by the network device.

For example, as shown in fig. 12, the terminal device is configured with uplink carrier 1-uplink carrier 3, and BWP1 and BWP4 are configured on uplink carrier 1, where the activated BWP is BWP4, the activated BWP configured on uplink carrier 2 and the activated BWP configured on uplink carrier 3 is BWP3, where the BWP with the lowest frequency among all BWP activated by the terminal device is BWP4, and the BWP with the highest frequency is BWP2, and then the reference DC position may be a specific position between the BWP4 and BWP2, such as the center frequency position DC position 4.

Example 3: the first BWP set comprises all upstream BWP of the network device configuration and all downstream BWP of the network device configuration.

Example 4: the first BWP set comprises all upstream BWP configured and activated by the network device and all downstream BWP configured by the network device.
